NTSB issues urgent safety recommendations on CF6-45/-50 engines

The US National Transportation Safety Board issued two urgent safety recommendations to FAA regarding CF6-45/-50 series engines prompted by four recent incidents in which aircraft experienced uncontained engine failures owing to failed turbine disks.

None of the incidents led to accidents, but NTSB is concerned that future similar events "present a direct hazard to an airplane and its passengers because high-energy disk fragments can penetrate the cabin or fuel tanks, damage flight control surfaces, or sever flammable fluid or hydraulic lines."
